Reduced dynamics
text:
In quantum mechanics, especially in the study of open quantum systems, reduced dynamics refers to the time evolution of a density matrix for a system coupled to an environment. Consider a system and environment initially in the state ρ S E and undergoing unitary evolution given by U t . Then the reduced dynamics of the system alone is simply If we assume that the mapping ρ S ↦ ρ S is linear and completely positive, then the reduced dynamics can be represented by a quantum operation. This mean we
